I have and Cubase 12 works fine. No difference really. I did however do a clean install. I didn’t upgrade over windows 10. It’s much cleaner that way. I partitioned my drive and dual booted between win 10 and 11 until the win 11 drive was fully populated with all my plugins and working as I wanted it. I then removed the sin 10 partition.
As long as the computer once had win 10 then yes you can. I’ve done it twice now. I’ve also done a dual boot machine which to all intents and purposes is a computer without win 10
I’ve used Winn 11 but the removal of taskbar/start menu/Explorer functions made it too awkward to use. There was no discernable difference in the running of any of my programs. It did look better, though.
I went back to 10.
C13 has too many video glitches, often rendering the interface unresponsive.
I went back to C12.
Others have had no problems. C’est la vie. ymmv.
Seems a lot of people here have had good experiences with both. I’m not one of them.
But I’m retired and have plenty of time to install and re-install stuff from scratch if it doesn’t work out. I also have Cubase 9.5 through to Cubase 13 installed…
If I were a Pro and my business depended on it I’d probably still be on Cubase 9 and Windows 7!
(For reference, Kirk, in Star Trek V, when served with baked beans and bourbon, described it as “an explosive combination”.)
